Y.,'ASSIGNOR TO WOOD NEWSPAPER MA- CHINERY CORPORATION, OF NEW YORK, N. Y., A GORPORATION OF VIRGINIA WEB SPLIOING DEVICE Application filed July 2, 1927, Serial No. 203,153. Renewed September 17, 1931.

This invention relates to a splicing device for connecting the end of an expiring web to a fresh web roll.

The principal objects of the invention are to provide means for engaging the running vweb with the rotating fresh roll and pushing the web toward the roll in such a way as to operate upon it yieldingly at all points so as to insure that the web all the way across w will be evenly applied to the pasted roll and also to provide a non-mechanical device for this purpose.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing which is a side elevation-of a pasting device illustrating the web roll reel in end elevation and showing a preferred embodiment of this invention connected there with.

In this case the invention is shown as ap plied to a type of machine in which a. motor 10 through a worm and worm wheel 11 operates a reel 12 to turn the reel when the motor is running. This reel is shown as having arms radially arranged and supporting the web roll studs and web roll 14 as usual. Electrical connections are provided, but not shown in detail, by which the motor is stopped when the fresh web roll 14 is moved up to E to the position shown.

solenoid 18.

turned by hand to bring the parts into the This solenoid is mounted on an arm 20 which is mounted to swing on a pivot 21 and has a handle 22 for operating it from the dotted line to the full line position. When the paster is about to be made this handle is full line position ready for operation. Thedevice which applies the running web to the roll 14 is in-the form of a pipe 24 having a line of perforations 25 alon it on the side adjacent the running web. This provides a series of jets all the way along the pipe and throughout the width of the web. This is connected through a valve 26 with a hose 27 connected with a source of compressed air or other fluid. The solenoid 18 is provided with a lever 28 which operates the valve through its stem 29' to admit air into the pipe 24 from the tank 31. 1

In this way a blast of air throughout a straight line extending across the web is directed against the web. This blast forces the web from the full line to the dotted line position so as to make the paster. tion of the reel by the motor beyond this point disconnects the solenoid from the circuit. An ordinary spring behind the valve will close the valve 26, only the case of which is illustrated. This device can be swung up out of the way' until the next paster is'to be made. I have shown feeding belts 30 for feeding the web from the expiring web roll, also mounted on the reel 12 as usual.

By the use of this blast of air mechanical devices, as brushes, rollers, etc., which have to be moved automatically, are eliminated. A minutely variable yielding means is provided for pressing the web against the roll. By that-I mean that any irregularity in the roll will have no effect on the web pressing means at all, no matter how great the irregularity may be. web roll therefore will not result in any irregularity of the pressure of the web against the roll. The web is pressed against it with the same force, practically, in 1ts hollows as it is against the projections. This is an extremely uniform and effective means for accomplishing this purpose.

l/Vhen the switch 15 was opened by the mohandle, shown in dotted lines, was also turned The rota-' The irregularities of the ordinary.

down to the position shown. When the paster is made the operator pulls the handle of the switch 15 up to vertical position which closes the switch. Tn addition to turning the Mil) handle up to that position he pulls it back which pulls the switch arm out beyond the end of the roll 14 where it stays until again manipulated. After the roll has passed it he pushes the handle" back so that the switch arm comes into the path of the roll. The switch then is in a position ready for the next roll to operate it again when it comes around.

Although I have illustrated and described only one form of the invention I am aware of the fact that modifications can be made therein by any person skilled in the art with-- out departing from the. scope of the invention as expressed in the claims. Therefore. I do not wish to be limited in these respects but what I do claim is 1. In a splicing device for a web feeding mechanism, the combination with means for guiding the web along a path near a fresh web roll, of a source of compressed fluid, and means for directing jets of fluid against the outer side of the traveling web to force it against the web roll to form the paster.

2. In a Web splicing device, the combination with a movably mounted and rotatable web roll, of means for moving the web roll bodily toward the traveling web, and means for directing an air blast against the traveling web to force it out of its path and into contact with said web roll.

3. In a web splicing device, the combination with a movably mounted and rotatable web roll, of means for moving the web roll bodily toward the traveling web, means for directin an air blast against the traveling web to force it out of its path and into contact with said web roll and means whereby the movement of the web roll bodily toward the web will be interrupted before the air blast is a plied.

4. In a we splicing device, the combination with a movably mounted and rotatable web roll, of means for moving the web roll bodily toward the traveling web, means for directing an air blast against the traveling web to force it into contact with said web roll, and means whereby rotation of the web roll on its own axis will control the application of the air blast to'the web.

5. In a web splicing device, the combination with a source of compressed fluid and a pipe extending along the web crosswise and having perforations in its surface adjacent to the web, of a valve for admitting air to the pipe, whereby a blast of air in a series of jets will be forced against the web to force it out of its path into position for pasting.

6. In a web splicing device, the combination with a source of compressed fluid and a pipe extending along the web crosswise and having perforations in its surface adjacent to the web, of a valve for admitting air to the pipe whereby a blast of air in a series of jets will be forced against the Web to force it out of its path into position for pasting, and means controlled by the rotation of the web roll on its own axis for opening said valve.

7. In a web splicing device, the combination with a source of compressed fluid and a pipe extending along the web crosswise and having perforations in its surface adjacent to the Web, of a valve for admitting air to the pipe whereby a blast of air in a series of jets will be forced against the web to force it out of its path into position for pasting, a solenoid, means for operating said solenoid at a predetermined time, and means connected with said solenoid for opening the valve.

8. In a web splicing device, the combination of afresh web roll adapted to rotate on its own axis, means for guiding the running web adjacent to it but out of contact with the surface of the fresh web roll, a pivoted arm, an air pipe on said arm extending across the web on the side of the web opposite the fresh roll and constituting means for deflecting the running web out of its normal path and against the fresh roll, a handle for moving said deflecting means into and out of position, and means for introducing air under pressure into said pipe, said pipe being perforated along its surface nearest the web, whereby a blast of air will issue from the pipe to force the web out of its paltlh into pasting position against the web ro 9. In a web splicing device, thecombination with means for supporting a fresh web roll and means for guiding the running web adjacent to the fresh roll, of means for directing a blast of air against the running web to deflect the running web toward the fresh roll at the time of splicing.

In testimony whereof I have hereunto affixed-my signature.
